More information on our sequential gearboxes can be found here. Straight-cut (spur) or helical gear ratios (including overdrive options) and numerous gear lever options allow customers wide scope for optimising QBE69G to suit individual requirements. Technical highlights include, 90mm shaft centres, integral oil pump, modular gear cluster, drum type sequential gearchange system, open face dog design on both gear and drive disc, producing a fast, positive gearshift. With 90mm shaft centres, this compact unit has been proven at over 1,200 whp. Proven in circuit, rally, drift, and drag racing.ĭesigned for high horsepower applications where the standard gearbox is no longer capable of coping with the power, and ratios suited for motorsport and a sequential gearchange are required. The QBE69G is our largest, heavy-duty, 6 speed, RWD, sequential gearbox. (if my current vintage race car project get's classed with the cars that 20years newer with motors 2-3x the displacement like the last one, i'm putting on of these in ) Attachments sequential.jpg (4.6 KiB) Viewed 3596 times hpattern shift.jpg (4.71 KiB) Viewed 3596 times tre-inline.jpg (3.SKU: QBE69G Categories: Gearboxes, Sequential I recall seeing the barrel/drum selector in a old ( 60's) ZF racing trans axle apart on the bench at the shop one time - looked like a PITA to work on. John, FWIW, you can clutch-less a shift a h pattern Hewland MK box ( Hewland also offer sequential on the old FT200 design ), the Quaife gear set for the 2000E box was a little more agricultural so I never really tried to clutch-less shift it ( not being critical here, its a good thing because you can't change the gears in situ like you would a trans axle) its light a 40 Lbs ( under 20 kilos) I think they have it worked up for the ford bell housing as well but not 100% sure here. you end up with a compact 4, or five speed box using Hewland MK gears so you have lots of choices, shifter can be configured for h-pattern or sequential. The one I like is collaboration between TRE ( taylor not toyota) & elite, it uses Staffs, Hewland case/guts and Elite ( not lotus) parts to convert to inline. Lots of food for thought arising from a question about who makes the thingiesīy the way this is a neutral emoticon which raises the question about finding that so special gear with a sequential box where my H shaped gear change has neutrals everywhere I can imagine that back in the day the drivers swooned over that facility. road or competition isn't the possibility to change, let's say from 4th down to 2nd without having to go through 3rd a big plus? I don't think so with such basic designs like the Quaiffe I think that the attraction for me in the Quaiffe sequential box was that it had 5 or 6 gears!īut I ask this question what are the advantages of a sequential change?ĭoes sequential automatically mean "clutch-less" gear changes i.e. The old Ford/Lotus 4 speed gearbox really set the standard way back when & even today is still pretty damned good as fat as smoothness & positivity in gear change. Strangely I was only thinking this afternoon, why bother? In any case I don't think that it would fit in the Elan's backbone without modifications. It being some time ago I don't remember properly but I think that the barrel selector was in the gearbox casing & the back & forth motion gear lever slotted into it the other box of bits (whatever it did) was fastened to the side of the casing. ![]() Yes it definitely utilized a barrel selector or what I would describe as a cylindrical cam, not being so up to speed on the technology. The "box" you saw might house the barrel and its end of the selector forks. ![]() It could be that Quaife is using a barrel selector system as was common in F1 a few years ago (maybe still is). ![]() GrUmPyBoDgEr wrote:There appeared to be a relatively large "box" on the side of the gearbox which supplied the clutch gear change "signal" or whatever but in any case the clever bit of gubbins that does all of the gear change, clutch thinking and or mechanical actuation etc. ![]()
